for releasing the holding means shown in Fig- On the back near the loweredge of the plate nre 4, IB, projections 32 are formed Whichvare adapted55 Referring now to the drawing in which I illusto fit into notches '33formed vin the bottom rail i3. By means of screws 34 passing through theprojections 32 and into the bottom rail the plate E8 is held inposition. Being thus located the screws are usually below the level ofthe eye and therefore inconspicuous and relatively concealed.

From the foregoing, it will be understood that any suitable advertisinglegend may be pasted, printed or otherwise displayed on the plate Il,and that such advertising legend may be changed from time to time byremoving the screws 34, withdrawing the plate I8 and thereafter removingthe plate Il and substituting therefor a similar plate carrying otheradvertising.

The lower part of the front surface of plate I8 is treated in anysuitable way to form a surface 35 upon which matches may be struck, suchfor instance as having cemented or otherwise secured thereon a suitablecomposition or indeed roughening the surface of the plate itself. Theremainder of the surface of the plate I8, is'such that memoranda may bewritten thereon and easily erased by any suitable means, such as by a.damp cloth.

In the construction of my device, I preferably mold the plates I1 and I8of a suitable plastic material, but it will be understood that any othersuitable material may be used, such for example as any suitable papermeans or paper board having a suitably prepared surface.

Referring now to Figures i and 5, in which parts similar to those abovedescribed are indicated by similar characters, it will be seen thatinstead of the projections 32 and screws 34 for retaining the plate I 8in position, I provide means entirely concealed behind the plates, suchfor eX- ample as a notch 38 formed in the back of the plate iS adaptedto cooperate with the upper end of a leaf spring 39 secured in anysuitable way to the back of the lower rail i3 or confined between saidrail and the frame support. The front portion of the lower rail I3 overthe hole 21 in the modification shown in Figure 4 is cut out as at 40 toprovide a rectangular aperture through which a tool such as shown inFigure 6 may be inserted from a point outside the frame, and by whichthe spring E9 may be pressed away from the plate I8 and out ofengagement with the notch 38 and permit the same to be withdrawn. Oneadvantage of this method of securing the plate I B in the device is thatit is less obvious how the plate may be removed and particularly how thespring 39 may be moved to inoperative position and thus prevent theremoval of the plates l1 and I8 by persons not authorized to do so. Itwill be understood that the device shown in Figure 4 may be assembled bypushing the plates I7 and I8 into the grooves as above described untilthe spring 39 drops automatically into the notch 3B, a position whichmay be described as their home position.

While I have described what now seems to be the preferred embodiment ofmy invention, it is conceivable that various modifications in theconfiguration, composition and disposition of the component parts goingto make up the same may occur to those skilled in the art, and thatvarious changes in the form, proportion and minor details may beresorted to within the scope of my invention.

5. A device of the class described comprising plate means having asurface suitable for recording memoranda thereon and from which the samemay be erased, in combination with means for mounting said plate meansupon a support, said mounting means comprising a frame having a toppiece adapted to serve as an abutment for said plate means, and a siderail depending from each end of said top piece provided with a grooveopen at the bottom between which said plate means is adapted to slideand be retained thereby with the front surface of said plate means andfront surface of said side rails and a portion of said top piecedisposed in a common plane, and means for retaining said plate means inposition surface of one of said plates disposed against said abutment,said retaining means comprising a'notch in the backL of said plate meansand a leaf spring mounted on said frame adapted to cooperate with saidnotch.

6. A device ofthe class described comprising plate means having asurface suitable for recording memoranda thereon and from which the samemay be erased, and means for mounting said plate means upon a support;said mounting means comprising a frame having spaced groove meansbetween which said plate means is adapted to slide and be retainedthereby, and an aperture; in combination with means concealed by saidplate means for retaining thesame in position, said retaining meanscomprisinga notch in the back of `said plate means and a leaf springmounted on said frame adapted to cooperate with said notch and beingoperable from a point outside of said frame through said aperture.
